From 423e40200a8f6cc45adc2a6bb3fc8a6db95f6ed6 Mon Sep 17 00:00:00 2001 From: Story Crater Bot <19826264+Riotpiaole@users.noreply.github.com> Date: Thu, 23 Jul 2026 07:29:51 -0700 Subject: [PATCH] =?UTF-8?q?refactor(argocd):=20consolidate=20Applications?= =?UTF-8?q?=20(39=E2=86=9235)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Merge related Applications using multi-source pattern and PostSync hooks: 1. ingress-config ← wildcard-cert + homelab-ingress (2→1) - Both in k8s/bootstrap/ingress/, now use kustomization - Certificate deployed before Ingresses (wave 1) 2. homarr ← homarr + homarr-patches (2→1) - Added PostSync hook source (fix-probes-job.yaml) - Patches run after Helm chart deployment 3. temporal ← temporal + temporal-db-secret-sync (2→1) - Added PostSync hook source (copy-job.yaml) - DB secret sync runs after Temporal deployment 4. Removed duplicate: ingress-nginx Application - ingress-nginx-bootstrap (bootstrap) is working - Removed redundant ArgoCD-managed ingress-nginx - Eliminated duplicate DaemonSet Skipped: cert-manager + cert-manager-issuers -
